GAS-BURNER.

Specification of Letters Patent.

Patented Oct. 26, 1909.

Application filed September 1, 1608. Serial No. 451,216.

To all whom it may concem:

Be it known that I, THOMAS STANLEY PHILPOTT, a subject of His Majestythe King ployed and a pilot light for re-lighting the of Great Britainand Ireland, residing at 256 Lambton Quay, Wellington, in the ProvincialDistrict of lVellington, in the Dominion of New Zealand, haveinventedcer-' tam new and useful Improvements in or Relating to Gas-Burners, ofwhich the followmg is a specification.

This invention relates to gas burners:

wherewith incandescent mantles are emmain supply of gas to the burner.

Hitherto a by-passfor admitting a supply of'gas to a pilot light hasbeen constructed 1n 1 the following way In a tap fitted to a burner,and-which is operated each'time the burner is brought'into use,agroovehas beenprovided in the plug of the cock, whichgroove allowed asupply of gas to pass to a pilot light when the cock was turned oif. In

another system, which is usually designated a pilot service, a number ofburners are supplied from one common gas main and" the pilot lights forsuch burners are supplied from an independent and common pilot gaspipe.In this case the whole of the burners are extinguished by a cock usuallyat some distance from the burners and the pilot gas tube is connected tothe main on the side of the tap remote from the burners. The pilot gaswas led to the gas burner by means of asmall tube connected to a nippleoutside the burner and it was therefore necessary to make a considerablenumber of bends in the small tube and further there was difiiculty inremoving the socket by which the said tube was connected to its nipplein the case of renewals, or for cleaning purposes. The result was thatcorrosionrapidly set up in the bends of the small tube and it wasimpossible to remove the tube and clean it owing to thebends preventingthe entrance of a wire and the difliculty or impossibility of removingthe socket after it had been in use for some time.

The object of my invention is to provide a ilot tube in a pilot servicewhich is practically straight so that there is very little lodgment fordeleterious matter within the tube and so that a wire can be readilypassed through the tube, the parts being so constructed that the burneritself can be readily taken apart and cleaned.

A further object of my invention is to pro vide means whereby any burnerin a cluster of burners supplied by a common gas main can be readilyregulated and adjusted independently of the other burners in the clusterwhereby the illuminating power of the burners may be readily equalized.The drawings illustrate the form which I prefer my invention to take.

Figure 1,'is an elevation partly in section of a chandelier having threeburners, Fig. 2, is a sectional plan on line A A Fig, 1, Fig.

3, is a diagrammatic view showing the piping.

The main gaspipe 1 is connected to a base consisting of a boss 2 havingan integral well 3. Branch pipes4= lead from the well 3 and are suppliedat their outer ends with a base 5 upon which is supported a burner 6known as the Avon top burner. The base 5 has a neck 7 and a collar 8.The gas passing from each branch pipe 4 to its burner is readilyregulated by a screw 9 having a milled head 10 and a conical end 11. The

said conical end being capable of closing upon a valve seat-12 formed inthe burner. A lock-nut 14 is adapted to lock the screw after itsadjustment has been efiected. The pilot gas tube 15 is connected to theboss 2 wherein a triangular channel 16 is formed, communication betweenthe apexes of the triangle and the exterior of the boss being closed byscrews 18. Holes 19 are formed from the exterior of the boss to thetriangular channel 16 and are fitted with plugs 20 provided with holes21 extending throughout nearly their whole length.

Holes 22 at the end of the'plugs and at the top thereof meet the holes21, which are traversed by screws 23 having holes 2 and by turning thescrews 23 the holes 26L will allow more or less gas to pass as desired.

Each hole 22 receives a pilot tube 26 which is practically straight andpasses through a groove 27 in the collar 8 and thence through the burner6. The tube 15 is carried back to a position beyond the main tap 28 (seeFig. 3) where it is connected to the main by a tee 29 or anyotherordinary means.

I have shown the'pipesl and 15 exposed to view, but if desired they maypass inside a casing in a well known manner.

When it is desired to clean the pilot tube 26 or the base '5 the burner6 is unscrewed from the base 5 and the pipe 26 is unscrewed from theplug 20 and the base is then unscrewed from the branch pipe 4: and thescrew 9 removed leaving all the parts in means for supplying gas tothebase, a

burner fitting the base, a hollow plug projecting below the collar and apractically straight pilot tube screwed into the-plug and passingthrough a groove in the said collar and into the interior of the burner,substantially as set forth.

2. In a gas system employing apilot service, a burner base having a neckand collar, means for supplying gas to the base, a burner fitting thebase, ahollow plug passing below the collar, a practically straight tubescrewed into the plug and passing through a groove in the-said: collarand into the interior of the burner, and a screw fitting the base andhaving a milled head and conical end adapted toclose upon. a valve seatwithinthe base and: a lock-nut upon. the screw,- substantially as setforth.

3.. Ina gas system' employing a pilot service, a burner base having aneck. and collar,

a base consisting of a bossand an integral well, branch pipes leadingfrom the said well, a burner base having a neck and collar with whichthe branch pipe communicates, a burner fitting the base, a hollow plugprojecting below the collar and a practically straight pilot tubescrewed into the plug and passing through a groove in the said collarand into the interior of the burner, a pilot gas pipe connected tothebase and communicating with the hollow plug, substantially as set forth.

41:. In a gas system employing a pilot service, abase consisting of aboss and an integral well, there being a triangular channel in the boss,screws closing the apexes of the channel, hollow plugs communicatingwith the channel,.pilot tubes communicating with the hollow plugs, andmeans for supplying gas to the channel, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two witnesses.
